Mkay, I know it's small, but I don't see a lot of shows (Okay, I've only seen all these roles on film, I've never seen anything on stage), so I don't know many other roles.
*Disclaimer~ Okay, I don't know what to expect from the Wedding Singer, as I saw the Adam Sandler movie that the Broadway Musical is based on, and I don't know how it was turned into a musical, as the movie soundtrack is a bunch of songs from the 80's... So I'm not sure about Julia's role, but if it's anything like Julia in the movie, I'm interested...
